Top Priorities (5)
Content-Security-Policy header is missing
Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.
HSTS header is missing
Without HSTS, a network attacker can downgrade the very first connection to HTTP and steal the user's session.
No Content-Security-Policy header found
Without a CSP, a single XSS bug can exfiltrate everything users type — credentials, payment data, session tokens.
Page weighs 13.8 MB (4.9 MB transferred)
Informational: total page weight (uncompressed) and bytes actually transferred over the wire.
1 image-in-link without alt text
Image-only links with no alt create empty links — screen-reader users hear 'link' with no destination context.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
€574 investment → €6,326/month returns + EUR 120,500,000 risk avoided
Figures combine localized regulatory fine ceilings, search/conversion value priced against local CPC, and bandwidth waste estimates. Results depend on implementation quality and audience composition. Not legal or financial advice.
Conversion barriers
8 barrier(s) likely increasing bounce by ~29%.
- Page takes 24.4s to loadUsers abandon at ~3s — you're 21.9s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- Page feels frozen for 4.1sClicks on the primary CTA are ignored while JavaScript runs→ Break up long tasks; defer non-critical JavaScript to post-hydration
- No HSTS headerReturning visitors are briefly exposed to downgrade attacks on first request→ Set Strict-Transport-Security: max-age=31536000; includeSubDomains
- No Content-Security-Policy headerHigher XSS blast radius — one compromised script can exfiltrate the checkout form→ Ship a reporting-only CSP first, then enforce once violations are clean
- Layout shifts during page loadContent movement causes mis-clicks on CTAs and form fields→ Add width/height to images; reserve space for late-loading embeds
